The comments pick up on statements Bernier made Sunday, acknowledging that Canada is a "huge and diverse" country. He criticized remarks Trudeau said in Toronto on Friday at the opening of the Taste of Danforth street festival — near the site where a gunman opened fire on diners last month, killing two and injuring 13 people.

Trudeau told the crowd that resilience comes from "different perspectives, different backgrounds, different cultures coming together and celebrating the same things." Differences are a source of strength and "never a source of weakness," he said.

"Having people live among us who reject basic Western values such as freedom, equality, tolerance and openness doesn't make us strong," Bernier tweeted, adding that those who do not integrate and adapt Canadian values "don't make our society strong."

1/ Trudeau keeps pushing his "diversity is our strength" slogan. Yes, Canada is a huge and diverse country. This diversity is part of us and should be celebrated. But where do we draw the line?

2/ Ethnic, religious, linguistic, sexual and other minorities were unjustly repressed in the past. We've done a lot to redress those injustices and give everyone equal rights. Canada is today one of the countries where people have the most freedom to express their identity.

3/ But why should we promote ever more diversity? If anything and everything is Canadian, does being Canadian mean something? Shouldn't we emphasize our cultural traditions, what we have built and have in common, what makes us different from other cultures and societies?

4/ Having people live among us who reject basic Western values such as freedom, equality, tolerance and openness doesn't make us strong. People who refuse to integrate into our society and want to live apart in their ghetto don't make our society strong.

5/ Trudeau's extreme multiculturalism and cult of diversity will divide us into little tribes that have less and less in common, apart from their dependence on government in Ottawa. These tribes become political clienteles to be bought with taxpayers $ and special privileges.

6/ Cultural balkanisation brings distrust, social conflict, and potentially violence, as we are seeing everywhere. It's time we reverse this trend before the situation gets worse. More diversity will not be our strength, it will destroy what has made us such a great country.

The trouble with this stuff is that is was said one hundred and fifty years ago about the arrival of the Irish, and every generation since then. Jews, Italians, Chinese, Sikhs, the list is endless - none of them were welcomed, all were accused of not "fitting in"

The Liberals later released a fundraising message critical of the Conservatives and called on supporters to donate to "ensure that positive politics wins the day."

"Once again they're showing that they are entirely out of touch with Canadians and this country's commitment to inclusion," it read.

Tory MP says Bernier's views don't reflect party

One Conservative MP says Bernier's comments do not reflect a view held by the party as a whole.

Newcomers hesitant of integrating into Canadian society applies to a "minute number of people coming to Canada," Calgary Forest Lawn MP Deepak Obhrai told HuffPost Canada in an interview.

"Most people coming to Canada seek freedom, opportunity, like all other Canadians who have come here before that have come to this country," Obhrai said, warning that it's important to recognize this trend, but to avoid falling into a "trap" of generalizing the habits of a few.

Immigrants are attracted to Canada because of what the country offers, the former Conservative leadership candidate said. Obhrai said his opinion on the issue has been shaped by his own experience as a minority, and from his travels around the world on behalf of the government.

"Yes, there is discrimination in this country; yes, we have seen that happen," he said. "But gradually we are overcoming those barriers and we are becoming a country that is admired around the world."

The Beauce MP's views have previously clashed with the party leadership by holding views contrary to the party line.

Bernier lost his role as innovation critic for the Official Opposition earlier this year as punishment for sharing a chapter from his book on his website, opposing Canada's supply management system.
